WINDOW- GUARD Specification of Letters Patent.

Patented Aug. 11, 1908.

Application filed February 8, 1908. Serial No. 414,954.

To all whom it may concern:

Be it known that I, HENRY H. ASHLOOK, a citizen of the United States, residing at Kansas City, in the county of Jackson and State of Missouri, have invented a new and usefulIVindow-Guard, of which the following is a specification.

This invention relates to guards for windows, the same being designed for use as gratings to protect show windows and the like or as auxiliary closures for window openings so as to prevent persons from falling therethrough.

The object of the invention is to provide a foldable or collapsible guard made up of suitably connected members, there being means provided whereby said members are limited in their movements by stop devices so that they are held, when the guard is extended, in such position as to enable the guard to be conveniently collapsed.

Another object is to so arrange and connect the parts of the guards as to enable the entire guard to be folded into a bundle of the same thickness as the width of any one of the members.

. Another object is to provide a guard which can be readily placed in or removed from position and which is simple, durable and efficient.

With these and other objects in View the invention consists of certain novel features of construction and combinations of parts which will be hereinafter more fully de' scribed and pointed out in the claims.

In the accompanying drawings is shown the preferred form of the invention.

In said drawings: Figure 1 is an elevation of the guard, the same being shown applied and extended. Fig. 2 is a view showing the same folded. Fig. 3 is a detail view of one of the joints and showing the stop devices adjacent thereto. Fig. 4 is a perspective view showing a modified form of guard partly folded.

Referring to the figures by characters of reference, 11 designate parallel strips, one of the end strips being provided with hinges 2 for connecting it to the window casing A while the other end strip has a suitable lock 3 for detachably fastening it to the window casing. Any desired number of these strips may be employed and they are all connected by means of links as shown. Every two adjoining strips 1 have pivotally connected intermediate links 4 pivoted thereto, said links being so located that when they are folded they assume positions between the strips 1 to which they are fastened. All of the links are of the same length, and the strips 1 are preferably of the same width as these links so'that when the guard is folded the same will occupy a space no wider than any one of the strips or links of which it is formed.

In addition to the intermediate links above referred to upper and lower sets of stop links are also utilized as connections between the strips 1, each set of links consisting of pivotally connected members 5 and 6. These members lap and are pivotally connected as shown at 7 and the member 6 has a laterally extending ear 8 integral therewith and disposed, when the links are folded together, to abut against the wall of a notch or recess 9 formed in the lower edge of link 5, thus preventing the links from swinging past each other while the guard is being folded. When the strips 1 are pulled away from one another the stop ears 8 come into contact with shoulders 10 formed adjacent the ends of links 5, thus limiting the extension of the guard. When the ears 8 are in contact with the shoulders 10 the pivots 7 are located out of alinement with the pivotal connections between the links and the strips 1 and it will therefore be apparent that by pushing the strips 1 toward each other all of the links will be caused to fold together until they assume positions between the adjoining strips 1 whereupon further movement of the guard will be prevented by ears 8 becoming seated in notches 9.

A device such as herein described can be readily connected to a window casing by means of the hinges 2 and when it is folded it will, as before stated, occupy a space equal to the combined thicknesses of thestrips 1 and links 4 and of the same width as one of the strips 1. By pulling onthe strip 1 containing the lock 3 the guard can be quickly extended until the ears 8 are brought against shoulders 10. When thus positioned the device will constitute an efficient guard and will also present an attractive appearance.

Although the guard as heretofore described has pivotally connected links between every two strips 1 it is to be understood that if preferred, and as shown in Fig. 4, each link 11 can be pivotally connected directly to the strips 12 as indicated at 13. With this construction the guard can fold together in the manner heretofore set forth so as to occupy the minimum space.

What is claimed is:

1. A guard comprising parallel strips, links connecting every two strips and ar ranged in superposed pairs, said strips and links being foldable with their longitudinal edges in the same parallel planes, and means carried by the links for limiting the extension of the device and to hold the links out of alinement.

2. A guard comprising parallel strips, superposed pairs of connecting links interposed between every two adjoining strips, said links being foldable between the strips, and said strips and links when folded constituting a bundle of the same width as one of the links or strips.

3. A guard comprising parallel strips, pivotally connected links arranged in pairs and disposed between the adjoining strips, said links and strips being disposed when folded with their corresponding edges in the same planes, and means upon the adjoining ends of the links of each pair for limiting the relative movements of said links, said links being maintained thereby constantly out of alinement.

4. A guard comprising parallel strips and pivotally connected sets of links interposed between every two adjoining strips, said guard being foldable into a space of the same width as one of the strips and of a thickness equal to the combined thicknesses of the strips and series of links, and cooperating means upon the links of each series for limiting the extension of the links to prevent alinement thereof.

In testimony that I claim the foregoing as my own, I have hereto affixed my signature in the presence of two witnesses.
